Hi. I have some pills and I have had them tested. Each contains 135mg. I am going to a party that lasts 9 hours. My plan is to take 1 at the start of the party, then some hours later, take another whole 1. Would doing it like this last me the full 9 hours? I read that when you redose, your suppose to take half of your original amount, so this may not be the best method. The other option is to take 1 at the start of the party, then some hours later, take a half, then some more hours later take another half. So its the same amount as the first plan, but just the second pill is split up into 2 parts instead. Would this be a better plan?
